II. Understanding Capacitor Charging
A. Basics of Capacitor Charging
The charging process of a capacitor involves the accumulation of electric charge on its plates when connected to a voltage source. The voltage across the capacitor increases over time, following an exponential curve defined by the time constant (τ), which is the product of resistance (R) and capacitance (C) in the circuit. The time constant determines how quickly the capacitor charges to approximately 63% of the supply voltage.
B. Applications of Capacitors
Capacitors are utilized in various applications, including:
1. **Power Supply Systems**: Capacitors smooth out voltage fluctuations and provide energy storage for power supply circuits, ensuring stable operation.
2. **Signal Processing**: In audio and radio frequency applications, capacitors filter signals, allowing only specific frequencies to pass through.
